2 Claims.

y, provide a curtain actuator wherein the parts are positively operative and not susceptible to the development of ready defects.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings: v

Figure 1 represents an elevational view, partly in section, showing a rear window curtain and the operating means therefor.

Figure 2 represents a fragmentary enlarged detailed sectional View of the bearing for the screw shaft.

Figure 3 represents a diagrammatic view disclosing the electrical connections between the electrical devices involved.

Referring to the drawings wherein like numer als designate like parts, it can be seen that nu-` meral 5 represents the rear portion of an automobile body, while numeral 6 represents the usual rear window equipped with a shade 7 on the customary spring roll 8. Numeral 9 represents the usual curtain and rod which, at its ends, is provvided with pins 10 to which the strands 11-11 are connected at their upper ends. These strands extend through guide tubes 12 in the top portion 13 of the rear seat and connect to the outer ends of the rocker arms 14.

The curtain operating mechanism, generally referred to by numeral 15, is situated behind the 40 upholstering of the rear seat and consists of a V-shaped frame 16 having a block 17 at its lower apex and into which the smooth end of the vertical screw shaft 18 is disposed, the shaft, at its lower end, engaging the ball bearing 19 sup- .45 ported by the removable insert 20. A cross member 21 on the frame 16 supports the reversibly wound motor 22, to the armature shaft of which the upper end of the shaft 18 is connected. Numeral 23 represents an internally threaded collar adapted to be bent vertically by the screw 18 when the motor 22 is energized. Link members 24-24 extend `from the collar 23 to the inner ends of the rocker arms 14, the rocker` arms 14 being provided with adjustable counterweights r`.55 25, as clearly shown in Figure 1.

A (li-electric plate 26 is mounted on one side of the frame 16 and carries the two switches v27-28, each being provided with spring contacts af-b. IThese are normally closed switches 27-28 and are only opened when engaged by the arms 14.

Referring to Figure 3, it can be seen that numeral 29 represents the automobile storage battery from which extends the lead 30 to the brush c of the motor 22 and also to the reversibly wound coils 3l-32 on one pole of the motor. The other 65 brush d` has a conductor 33 extending to the armature 34 of the relay, generally referred to by numeral 35, the relay 35 having the coils 36-36, with the armature 34 being engaged with a grounded contact 37 when the relay is'energized. 70

The coil 38 on the other pole of the motor is connected by the conductor 39 to one side of one of the coils 36, while the other side of this coil is connected by the conductor 40 to the contact a of the switch 28. The remaining coil on the last y'15 mentioned pole of the motor 22 is connected by"`-` the conductor 41 to one side of the other coil 36 of the relay 35, while the remaining side of this coil 36 is connected to the contact a of the switch 27. The remaining contacts b-b of the switches 27-28 are connected by conductors 42 to the contacts 43-44 of the drivers convenience switch, generally referred to by numeral 45, the same being provided with a contactor 46, grounded, and engageable with one or the other of the contacts 43-44. Thus it can be seen that when the contacter 46 is engaged with one ofthe contacts L3- 44, the corresponding coil 36 becomes energized, attracts the armature 34 and establishes a ground for the motor 22. The motor will now operate the screw 18 and the screw 18 will in turn lower the curtain until the corresponding arm 14 engages the contact va, of the `switch 27. This will disrupt the particular circuit involving the last mentioned coil 36, while the other switch 28 is still closed* so that when the contactor 46 of the drivers switch 45 is swung to the other contact, the motor will be operated in the opposite direction to lift the curtain. While the foregoing specification sets forth the 1 invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as I claimed hereinafter. Having described the claimed as new is:

1. An automobile curtain operator comprising a frame, a pair of rockable members on the frame., 11D

invention, what is 2. An automobile curtain operator comprising. a frame, a pair of rockable members on the` frame, each of said rockabie members being corinected at their outer ends to the curtain to be actuated, a reversible motor, a screw shaft driven by the motor, a threaded collar on the screw shaft, link members between the rockable arms and the collar, limiting switches for the motor infthe path of one of the rocker armsQcounterweights ad-A Vjustably mounted on the said rocker arms, and a. reversing switch for controlling said motor.
